Suddenlink, an MSO with about 1.3 million customers, isn't specifying where it's using the DTAs, but the boxes are being distributed to nearly 20 of the MSO's markets, from West Texas to West Virginia, according to a spokesman.

Suddenlink is using the one-way converter boxes to ensure that customers can still view basic channels on analog TV sets as those networks are migrated to digital. That work ties into Project Imagine, a bandwidth management and advanced services initiative that will see Suddenlink spend about $350 million in capex through 2012 "above and beyond" its regular spending levels.

Huawei has developed two standard-def DTA models – one that works on Motorola Inc. (NYSE: MOT)-based digital cable networks, and smaller version designed to run on either Moto or Cisco Systems Inc. (Nasdaq: CSCO) cable systems. Huawei's recent move into the DTA market applies competitive pressure on several other vendors, including Motorola, Cisco, Pace plc , Technicolor SA (Euronext Paris: TCH; NYSE: TCH), and Evolution Digital LLC, among others.

Web evidence
A tip on the Light Reading Cable message board directed our attention to some info on the Web that details Suddenlink's project and an image of the DTA the MSO is highlighting. The device doesn't bear Huawei's logo, but it sure looks like the DTA for Motorola networks that the Chinese vendor showed off at the Society of Cable Telecommunications Engineers (SCTE) Cable-Tec Expo last fall.

Getting Down With DTAs

The DTA highlighted on the Suddenlink Web site appears to be a model that works only on Moto-based digital cable networks.

Light Reading Cable reported last fall that both Suddenlink and Mediacom Communications Corp. had deals to buy DTAs from the Chinese vendor, with Suddenlink on board for at least 70,000 units if an initial batch of 7,000 tagged for early pilot efforts went well. Industry sources say Comcast is also taking a close look at Huawei's DTAs, but it's still unknown if the MSO has pulled the trigger on any purchase orders. (See Huawei Breaks US Set-Top Seal .)

Mediacom is deploying DTAs as well for its own analog reclamation activities. A Mediacom spokesman confirmed that the MSO is evaluating Huawei DTAs, but it's still not clear when or if Mediacom will be using them.

Huawei has been supplying optical gear to Suddenlink and Mediacom for some time. Mediacom announced last fall that it was using Huawei's OSN6800A platform to provide next-generation dense wavelength division multiplexing (NG-DWDM ) transport for a 4,000-kilometer backbone network touching portions of Missouri, Iowa, and Minnesota.

A Huawei spokeswoman declined to offer further comment on the company's DTA activity with U.S. cable operators.
